hygienic surfaces.


In terms of lined doors, the options include: X-ray protection, radiation protection, laser protection. Lastly there are features for fire and smoke resistance, and sound insulation (to 39 dB).


Material selection


From high-performance laminate (HPL) and glass-reinforced plastic (GRP) to anodised aluminium, and AISI304 stainless steel there are many choices in material to suit all applications.


Modular design – building on a basic model


doors support the maintenance of a sterile environment via hermetic closing action and easy clean qualities.


Early-stage specification considerations


So how do manufacturers convey the process when supporting an architect? To answer some of these questions you need to consider all the features, benefits, material choices and other options for hermetically sealing and cleanroom door systems. A large range of materials are available for the door leaf core and surface finishes, as well as the design of the door frames and sealing system. This ensures that manufacturers can accommodate a wide range of applications.


Every manufacturer worth their salt will have a local specification manager who will gladly guide you through all the options no matter how bespoke your requirements might be.


The available features and materials can be mixed and matched (within reason) to meet the precise needs of the healthcare facility you are working on. For hermetic sealing, the options include airborne pathogen and particle protection, and airflow interruption. The options for cleanrooms are water resistant with an inorganic core, and antimicrobial

As well as the many combinations there are door leaf formats including single leaf sliding, bi-part sliding, telescopic sliding, and swing doors, all of which can either be manually operated or automated to suit traffic flow and efficiency. By building on a basic model, many bespoke versions for special applications can be created. For example, protection against electrons, x-rays and gamma rays can be provided with the addition of a full surface lead insert within the door leaf, in the inside of the frame profiles as well as the plinth itself.


A certified smoke control door can be created by adding modified seals and a heat-absorbing core. Adding in a fire- retardant core and additional intumescent seals a fully EI30 door can be delivered. Besides offering a range of surface finishes and custom door leaf core, the doors can also be fitted with various sizes of windows, integrated blinds (manual or powered), and even laser protection according to specific requirements. Mechanical and electrical locks are available, as well as various models of cantilever-type handles. In summary, hygienic door systems are an essential part of preventing the spread of airborne pathogens and particles within healthcare settings.
